We're both in town tomorrow, and I asked her if she wanted to go then, she said she couldn't because she's in town with her mum, shoping, and she would probably go home after (When she said it, she was stuttering on some words), she shyed away from the topic and we started talking about other things, that interest us both.
^She did have to go shopping with her mum, I met her in town for FCBD.

Here's what's been happening so far:- (I'm 16 never had a girlfriend before)
There's this girl that I like, really like as in love, we're friends, we're both the same age, I'm really shy and so is she.
First off, we talk loads, and I mean loads (we talk about games TV, and music, stuff like that), when we talk we smile at each other and throughout the conversation we look into each others eyes, we don't look away, when I finish talking she'll ask me a question or tell me something interesting, when we first started talking she was always looking down, talking really quick and stuttering on some words, now it's not so much.
We both like almost all the same stuff, music games etc. (This isn't even half of what we share in common).
I've made her laugh once or twice, and she's only laughed at me when I've made a complete and utter fool of myself. When I stumbled, she was the only one to laugh, she was giggling to herself. Even when I made a barely funny joke, she was the only one to giggle.
In addition, if I need anything, like a pen or a pencil or some help, she'll always help with anything I need.
Finally when I asked for her number, she was pretty quick to give it to me, and said it so fast I had to half guess some numbers.
When I send her messages she usually replies, however sometimes she doesn't (only when I ask how she is/how her holiday is going so far)
When I was talking to the girl we had, what I thought was, an awkward silence because I couldn't think of anything else to say to her. It lasted about 25-30 seconds, when she finally said something the conversation carried on.
The other day, after school mine and her friend shouts "Her name have a nice walk home with my name"
She replys with "Why wouldn't I?!"
Her tone was defensive, as if she was sticking up for me, lol, but it was happy sounding, higher than her usual voice, she's done this a few times now.

The friend, is both ours, I told him that I liked her And the other day, I think, my friend whispered to me she likes me, but he denies it, so I don't know if he was just saying that or what. And now he's telling me I shouldn't ask her out, and that he doesn't think she likes me more than a friend. What gives?
And we are in the same classes at college, so I see her every day, although I don't often get to walk alone with her, as our friends walk home the same way to.
She's also told me personal stuff about her, like what music and stuff she listens to, books she reads, what uni she want's to go to, that her parents are thinking of moving away when she finishes college things like that.

In addition, when we were talking her eyes were biger than normal.
She was touching my leg with her foot as well, I think she knew she was, because she didn't stop,I just overexagirating this.

Don't you just hate how friends can be such ****** bags sometimes?

Well, my friend, 'the comedian' makes my jokes seem like utter s**t (sorry for the language), and I think the girl doesn't like me the same way anymore, all because my friend makes her laugh more than me.

I also sent her a message asking if she was coming into to college this morning, because she was late, and 'I' didn't get a reply, but when my other friend who is a girl sends her a text asking if she's coming in, she gets a text back saying she's going to be late.

I really like her, I think she is the most wonderful girl I have met so far, she has the nicest and kindest personality, we share a deep connection, but she was acting differently today, she was late, and was acting differently, she wasn't as talkative as she normally is with me, and was talking to other people she doesn't normally talk with (boys). She was also moody to.

What are your thoughts, as to why she's acting strange now?

Again today, she was acting strange, she didn't bother saying hello or anything to me, excluding me from almost everything.
Also she kept getting up with another girl who is our friend, and walking off.
She vanished from colleg today as well, and when our friend (boy) tried to ring and ask where she had gone, she didn't reply.

I think it may be my fault, because I didn't bother talking to her much yesterday and today.

I don't know, the 'comedian' is a good friend (and I don't think he is her type), I asked him what he thought, he said he thought it was going well between me and her, and I doubt she would've met anybody else.
I'll see how she is tomorrow, maybe she's had a rough couple off days, and I'll apologise to her for not talking to her today.
I don't know what else it could be.

We're talking again
She told me to watch some more MLP and the rest of SoI series on YouTube, because she was going to a house warming party (I hope she gets home safe) , and isn't able to play minecraft with me... but

I asked her what was wrong, but she said she didn't want to talk about it, so I moved onto a new subject.

Now I wan't to ask her to go to the cinema with me, again, but I am afraid she will say no. How should I ask her to go with me?

Also, I think, she may still have feelings for her ex, as they only broke up about 2 months ago.

I see you put the fact that she just broke up with the ex 2 months ago at the end of all of this.
It sounds like she does not know what her feelings are at this point.
